摘要

CsCaF3 crystals doped with Er3+ and Yb3+ ions have been studied using electron paramagnetic resonance spectroscopy. Several types of paramagnetic centers of rare-earth ions have been discovered, among which paramagnetic centers in unusual positions have been found. The parameters of the corresponding spin Hamiltonians are determined and possible structural positions of the observed centers are proposed.
